The Great Escarpment, which edges the central Southern African plateau, is a major geological formation in Africa (See "Geological origins" below). While it lies predominantly within the borders of South Africa, in the east it extends northwards to form the border between Mozambique and Zimbabwe, and in the west it continues northwards into Namibia and Angola. Different names are applied to different stretches of the Great Escarpment, the most well-known section being the Drakensberg (diagram on the right). The Schwarzrand and edge of the Khomas Highland in Namibia, as well as the Serra da Chela in Angola, are also well-known names.
